What is Gapup MCP?

A hosted Model Context Protocol server exposing 100+ business expertise tools for AI agents. Each tool returns a structured, audited, board-ready JSON deliverable in 1-30 seconds.

Pay-per-call via x402 (USDC + EURC on Base + Optimism). No subscription, no API gateway. The price is encoded in the response — agents pay what they consume.

Why agents use it

• Board-ready output — Zod-typed JSON, persona-stricte, no chat fluff
• Dual-audience format — `audience` param routes `human` (Mistral gold-standard, ~30s) vs `agent` (Cerebras qwen-3-235b, <5s)
• Source-grounded — citations, DOIs, evidence trails; no hallucinated facts
• EU-first moats — DVF Cerema + Géorisques for real estate, OFAC + EU + UK + UN + SECO + SEMA + DFAT for sanctions
• Free tier real — 100 calls/mo without credit card, no rate-limit games

License & usage

The contents of THIS repository (manifests, docs, SDK examples, governance files) are licensed under **MIT** — you can fork, translate, reuse the snippets, contribute back.

The hosted API at `mcp.gapup.io` is governed separately by the Gapup Terms of Service. The MIT grant does NOT cover commercial API usage at scale — that's a per-call x402 settlement.

The server implementation itself is private (closed-source). This repository contains zero server source code — only the public surface (manifests + docs + examples) that lets clients integrate with the hosted endpoint.
